This invention relates to grease retainers of the kind which are employed to form a seal about the rear axle of an automobile and for many other purposes where it is desired to prevent the escape of grease or oil.
The object of the invention is to provide a unitary device of novel and simple construction adapted to be readily installed for use and which will efiectively prevent the escape of grease or oil thereby.
Another object of the invention is to provide a novel and effective means for securing the packing in a unit grease retainer and for preventing the passage of grease or oil around the packing within the retainer.
And a further object of the invention is to provide a grease retainer having a double shell construction, one shell being arranged concentrically within the other, and providing a strong and substantial device capable of resisting severe blows without being distorted.
In the accompanying drawing illustrating a se lected embodiment of the invention,
Fig. 1 is a side view of the retainer partly in section. v Fig. 2 is a detail transverse sectional view on the line 2-2 of Fig. 1.
Fig. 3.. is a sectional view on the line 3-4 of Fig. 2.
v Fig. 4 is a detail view of the inner shell partly broken away and in section.
Fig. 5 is a detail plan view of a portion of the packing.
Fig. 6 is a sectional view corresponding with Fig. 2 and showing another form of the invent on.
Fig. 7 is a detail view showing one side of a part 'of the retainer.
Referring to the drawing, the packing Preferably comprises a ring made of leather or other suitable material having a tubular portion 8 to engage a shaft and a radial portion {which is securely held against rotation in the device. The outer shell, formed from sheet metal, comprises a rim l0 and a side H integral with one edge of the rim, and the radial portion of the packing is arranged within the ,shell against the inner ,face
of the side and abutting the inner face of the rim. The other edge of the rim is preferably turned inward to form a flange II. The inner shell is also formed from sheet metal and comprises a rim l3 and a side ll integral with one edge of the rim. The side ll of the inner shell is located opposite the side II of the outer shell and forms,
with the flange l2, one side of the device. The
inner shell is arranged within the outer shell with its rim l3 spaced a distance from the outer shell to permit parts of the inner shell to pass through the openings in the radial portion of the packing. Slots I5 are provided in the radial por- 5 tion 9 of the packing at spaced intervals and the rim of the inner shell is provided with projections I6 which extend through said slots and abut the side ll of the outer shell. The projections l6 and the side I I are welded together and the pro- 10 jections are preferably provided initially with welding tips It to facilitate the welding operation. The projections l6 abut the side ll of the outer shell and the welds l'l secure the inner shell rigidly to the outer shell. The edges l3 of the 15 inner rim l3 Between the projections I6 engage the packing and hold it tightly against the outer shell. A resilient ring preferably in the form of a coil spring I8 is arranged in the spring chamber l9 between the packing and the inner shell and 20 operates to hold the tubular portion of the packing in close contact with the shaft upon which The invention provides a retainer of strong and 3 substantial construction which will withstand without distortion the blows ordinarily employed for installing the retainer in a housing. The shells are welded together and the packing is rigidly secured in place between the shells against 40 relative rotative movement and with sumcient contact area between the packing and the shells to prevent passage of grease or 011 about the peripheral edge of the radial portion of the pack- 7 ing. The packing contacts the entire inner face 4 of. the side ll of the outer shell and with ,a portion of the rim of the outer shell and with the inner edge of the inner shell, with or without the washer 20. Slncethe inner shell is welded sewill tightly clamp the radial portion of the packing between itselif and the outer shell to prevent relative movement of the packing and shells and also to prevent the passage of grease or oil.
We do not limit the invention to the specific disclosure in the foregoing description and drawing but reserve the right to ,make any changes in the form, construction and arrangement of parts as may be necessaryor desirable for the many purposes for which grease retainers are employed and within the scope of the following claims.
We claim:
1. A grease retainer comprising an outer shell having a rim and one side, an inner shell having a rim and one side, the rim of the inner shell being spaced from the rim of the outer shell and the side on the inner shell being disposed opposite to the side on the outer shell, a packing secured within the shells and projections on the inner shell penetrating the packing and contacting the outer shell and secured to the outer shell.
2. A grease retainer comprising an outer shell having a rim and one side, an inner shell having a rim and one side, the rim of the inner shell being spaced from the rim of the outer shell and the side on the inner shell being disposed opposite to the side on the outer shell, the inner edge of the rim of the inner shell being spaced irom the side of the outer shell, projections on the inner edge of the rim of the inner shell abutting and welded to the side of the outer shell, and a packing having openings to receive said projections and secured between the side of the outer "shell and the rim of the inner shell.
3. A grease retainer comprising an outer shell having a rim and one side, an inner shell having a rim and one side, the rim of the inner shell being spaced from the rim of the outer shell and the side on the inner shell being disposed oppo- 5 site to the side on the outer shell, a packing arranged between the side on the outer shell and the inner edge of the inner shell and having spaced openings therein, projections from the inner edge of the inner shell extending through said openings and welded to the side of the outer shell, and a washer interposed between the packing and the inner edge of the rim of the inner shell and having openings to receive the projections on the inner shell. 1 4. A grease retainer comprising an outer shell having a rim and one side, an inner shell having a rim and one side, the rim of the inner shell being spaced from the rim oi the outer shell and the side on the inner shell being disposed opposite to the side on the outer shell, a packing having a tubular portion and also-having a radially extending portion secured between the side on the outer shell and the inner edge of the rim of the inner shell, a washer contacting the packing and adjacent the rim of the inner shell, said washer and packing having aligned openings therein and projections on the inner shell passing through said openings, the inner shell forming with the packing a spring chamber, and a spring arranged within said chamber and embracing the tubular portion of the packing.
